Severed metal bearing ore is placed in a vessel having a water inlet at the bottom and an outlet at the top. A propeller causes water to flow upwardly through the vessel and to be discharged through the outlet carrying gangue with it. Concentrate, which is heavier because it contains the metal to be recovered, does not rise to the level of the outlet and therefore remains in the vessel.
An apparatus for treating a slurry with ultrasound to improve separation based upon specific gravity comprises a plurality of modular conduit units (10, 11, 12) having substantially vertical walls defining a flow space through which a slurry may be pumped.

O. D. Ogundare et al. 303 In Figure 1(a), which shows the gold ore, about eighteen (18) peaks starting from 2= 15˚ to 2θ θ = 100˚ were observed while the extracted gold shown in Figure 1(b) revealed about five (5) peaks starting from 2θ = 45˚ to 2θ = 100˚. The SEM (Plate 1(a) and Plate 1(c)) shows that the morphology of the particles of gold ore from Itagunmodi
water consumption was 6.85 m3 of water per ton of dry ore (daily basis). If we consider that the gold content of this ore was 0,031 kg per ton of dry ore, it can be said that the "Reina de Oro" plant used a daily average of 21.79 m3 of water per kilogram of gold, being the yearly production of gold, estimated in 114.76 kg.
